OpenSea uses Cloudflare DNS as firewall protection to prevent DDoS attacks.

If you visit OpenSea NFT marketplace, you may encounter ‘Error 1020: Access Denied’.

One of the main reason you’re seeing this error, because you’re trying to access OpenSea from a restricted region.

If you read OpenSea Terms of Service, it stated that;

You agree that you will abide by these Terms and will not: Use the Service from a country sanctioned by the government of the United States.


Below is the list of countries sanctioned by the US government, but not limited to:

  • Belarus
  • Cuba
  • Iraq
  • Iran
  • Lebanon
  • Libya
  • North Korea
  • Syria
  • Venezuela
  • Yemen
  • Zimbabwe

If you’re from one of these countries, you may be blocked from accessing the OpenSea marketplace platform.

However, you may still encounter ‘Access Denied’ from OpenSea NFT platform, even if you’re in an allowed country.

It can happen when you’ve clicked many OpenSea links, or have many tabs open at the same time.

The firewall must have thought I was a bot and temporarily restricted your access to prevent DDoS attack.

Alternatively, waiting for half an hour and trying with a different browser, you access will then get whitelisted again.

If that waiting didn’t work for you, below are some ways to stop seeing Error 1020: Access Denied from OpenSea.

Let’s dive in already…
